To all whom, 'it may concern,.-

Be it known that LWALTER JAY TREMAN, a citizen of the United States ofAmerica, and a resident ,of Shelby, Richland county, Ohio, have inventedcertain new and useful Improvements in Pin-Spotters ,ofy which thefollowing is a specification.l

My invention relates to bowling, and has forits objects the constructionof a device that will afford facilitiesfor setting the pins in proper position rapidly, uniformly, and exactly on the same spot each time theyare' set Aup. i y

It consists, further, in the particular con` lstruction and arrangementof the parts shown and described. 4

I attain these and other objects by thev i mechanism illustrated in thedrawings, in

Figure 1 isa longitudinal section taken through-.the center of Fig. 2and detail of'. operating mechanism `with part of bowlingpins bro enawayto show end of spottin -1 pins inserted in aperture in bottom `of bowing-pins. VFig. 2 .is a top plan view of a bowling-alley, showing pinsset in proper position preparatory to forcing them below the surace ofthe alley. Fig. 3 is aplan view of the reciprocating pin-plate. Fig. 4is a top plan view of the operating-lever. Fig. 5 is a side view of Fig.4. Fig. 6 is a top view of part of the operating mechanism in dottedlines. Fig. 7 is a top view of an alley, showin the operating-leverlocated on the side o the alley. Figs. 8 and 9 are side and end views,respectively, of the bifurcated standard.

- Figs. 10 and 11 show a top and side view, re-

spectively, of the operating-lever. Figs. 12 and 13 show a side and endview, respectively, of the ring-bushing. Fig. 14 is a plan view of dtheoperating-rod, showing bifurcated en s.

ln the drawings, 1 represents an ordinary bowlin -alley. 4 In theconstruction of my devicel prefer to form a recess 2 and inclose it withthe cross-piece 3, which forms the end of the alley adjacent to the pit4. A longitudinal aperture 5 is formed in the center of the pit 4 andcommunicates with the recess 2. A bushing 6, having both ends enlarged,leaving a ring portion 7 1n the center, is fitted to the aperture 5. An'operating-lever 8, having its end 9 preferably turned at an angle to thebody portion, is pivotally journaled in the aperture in the rin 7 of thebushing.. It will be observed that t e bushing is so placed in theaperture 5 as to leave the angular end of the operating-lever resting onthe bottom of the recessed portion of the alley, with the ends of thespotting-pins 1() lying below the surface of the alley. A verticalaperture 11 is provided in the end of the pit 45, intersecting theaperture 5, into which the bifurcated lever-rod 12 is looselyfitted,with the ends 13 13 adapted to fit the flattened ends .14 of theoperating-lever and locking-lever 15.

A bracket a is secured to the top of the back-stop 15b and pivotally suports the locking-lever 15, which alines wit and is secured to thebifurcated end of the lever-rod 12, affording a means of impartingl anoscillating'motion to the` operating-lever, which in'turn reciprocatesthe' plate carrying the spotting-pins. I i

Aplate 16, having a series of spotting-pms 10Ysecurely fastened thereto,is provided and placed in the recess 2 and rests on-the top 1.71

of theI end 9 of the operating-lever 8. The

spotting-pins extend into the corresponding apertures 18 in the surfaceof the alley and when not in use lie below the surface. bowling-pins 19are provided with apertures 20, tapered or straight to fit-loosely theend of the spotting-pins. A back-stop 21, having a recessed portion 22,is securely fastened to the end of the pit.

A suitable elastic washer 23, preferably made of'rubber, is inclosed inthe recess 22. The aperture which is formed in the washer is madesmaller in diameter than the leverrod 12 and forced thereon to providefrictional contact therewith suflicient to retain the lever-rod at anypoint or position of its travel at the will of the operator andretaining the spotting-pins above or below the surface of the alley forthe purpose intended.

The operation of my device is as follows: When it is desired to set thepins, the operator presses down on the locking-lever 15. This pivots theoperating-lever in the ringbushing, imparting an upward movement to theend which is in contact with the bottom of the plate, forcing the endsof spotting-pins which are carried by the plate above the surface inexact and uniform position preparatory to the bowling-pins being setthereon. When the pins are set, the locking-lever 15 is pulled upward,pivoting the operating-lever The and forcing the angular end 9 to lie onthe bottom of the recess 2. This movement permits the plate to drop bygravity, carrying the spotting-pins below the surface of the alley. Aplate 25 keeps the operating-lever in place, the end contactingtherewith. To provide an indicator or guide to show when the spottin-pins are below the surface, the end of the ont pin 26 of the series ismade longer. When the bowling-pins are set upon the spotting-pins, thetop o the front bowling-pin will be above the plane of the other pins,indicating that the spottingins are not elow the surface of the alley.'Ilhe operating mechanism can be positioned on the side of the alley orsecured to the alley without recessing the bottom.

I do not confine myself to the exact arrangement or construction of theparts shown as slight alterations can be made Without deviating from theprinciple herein' involved.

Having fully described my invention, what I claim, and desire tosecureby Letters Patent, is-

1 Apin-spottin'gdevice for bowling-alleys, comprising an alley' havingapertures provided in one end, an angular plate having pins securedthereto and adapted to register with said apertures, a bushing, anoperatinglever pivoted in said bushing with one end adapted to contactwith the bottom of the angular plate, a rod secured to one end of theoperating-lever, means to impart motion to said operating-lever wherebythe angular plate is recilprocated.

2. n a spotting device for bowling-alleys, an operating-lever having oneend turned at right angles, a bushing adapted to pivotally support saidoperating-lever, a plate having pins secured thereto contacting'with theend of the operating-lever, a locking-lever secured to one end of theoperating-lever, means to impart movement to said plate to force thespotting-pins above the surface of the alley ity, an elastic washeradapted to frictionally contact with the lever-rod for the purposesetforth. l I

'3. In apin-spotter for bowling-alleys,l an operating-lever having oneend turned at right angles, a locking-lever secured to one end, abushing having enlarged ends with a contracted center portion forming aring and adapted to pivotally support said operatinglever, a platehaving spotting-pins secured thereto and adapted to fit loosely incorresponding apertures l rovided in the surface of the alley, means toorcethe ends of the spotting-pins above the alley-surface, means topermit them to drop below by gravity as described and set forth.

4. In a pin-spotting device, an operatinglever pivotally secured to thepit, one end of said operating-lever turned at right angles with thebody portion, a plate, spotting-pins secured to said plate, alocking-lever to operate said lever whereby the plate carrying the pinsis forced upward to make ends of the pins extend above the surface ofthe alley and to permit the plate to drop by gravity, a plate to holdthe lever in position, a washer fitted to the locking-lever tofrictionally hold it in place.

5. In a pin-spotting device, an operatinglever,'a plate, a series ofspotting-pins with the front pin made longer secured thereto,bowling-pins having apertures formed in the bottom, a locking-lever,means to force the spotting-pins below the surface, means to force thepins above the surface preparatory to setting the bowling-pins asdescribed.'
